To the Owner/Operator/Dealer
This Operator's Manual is an integral part of the safe operation of this machine and must be maintained with the
implement at all times. A Manual canister is provided on the implement where this manual can be properly stored.
If you lose or damage this manual a free replacement manual can be obtained from an authorized Rhino dealer or
by down loading the manual from the Rhino website www.servis-rhino.com
BEFORE YOU START! READ, UNDERSTAND, and FOLLOW the information provided in this manual, the AEM
Mower Safety manual and the tractor operator's manual carefully to learn how to operate and service your machine
properly. Failure to do so could result in personal injury to you and bystanders. All implements with moving parts
are potentially hazardous. Every effort has been made to ensure that this machine is safe, but operators must
avoid engaging in unsafe practices and follow the written instructions provided. The manufacturer has designed
this implement to be used with all its safety equipment properly attached to minimize the chance of accidents.
SAFETY FIRST. Completely read and understand the safety section of this manual before operating this
equipment. Do not allow anyone to operate this equipment who has not fully read and understood this manual.
Contact your Dealer to explain any instructions that you do not fully understand.
The care you give your Rhino Implement will greatly determine your satisfaction with its performance and its
service life. Carefully read and follow the instructions in this manual to provide you with a thorough understanding
of your new implement and its intended use and service requirements.
All references made in this manual to right, left, front, rear, top or bottom are as viewed facing the direction of
forward travel with the implement properly attached to the tractor.
Replacement Parts information is located in a separate Parts Manual. Rhino mowers use balanced and matched
system components for blade carriers, blades, cuttershafts, knives, knife hangers, rollers, drivetrain components,
and bearings. These parts are made and tested to Rhino specifications. Non-genuine “will fit” parts do not
consistently meet these specifications. The use of “will fit” parts may reduce mower performance, void warranties,
and present a safety hazard. Use genuine Rhino mower parts for economy and safety.
For future reference, record your Rhino product model number and serial number.

In order to reduce accidents and enhance the safe operation of mowers, Alamo Group Ag Division, in cooperation
with other industry manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower Safety
Practices video and guide book.
The video will familiarize and instruct mower-tractor operators in safe practices when using industrial and
agricultural mowing equipment. It is important that Every Mower Operator be educated in the operation of their
mowing equipment and be able to recognize the potential hazards that can occur while operating a mower. This
video, along with the mower operator’s manual and the warning messages on the mower, will significantly assist in
this important education.
Your Authorized Rhino Dealer may have shown this video and presented you a DVD Video when you purchased
your mower. If you or any mower operator have not seen this video, Watch the Video, Read this Operator’s
Manual, and Complete the Video Guidebook before operating your new mower. If you do not understand any of
the instructions included in the video or operator’s manual or if you have any questions concerning safety of
operation, contact your supervisor, dealer or Alamo Group Ag.
If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax AEM VHS
Video at (830) 372-9529 or mail in a completed copy of the form on the back of this page to AEM VHS Video 1502
E Walnut Street, Seguin, TX 78155. and request the VHS video version. Please include your name, mailing
address, mower model and serial number.
Every operator should be trained for each piece of equipment (Tractor and Mower), understand the intended use
and the potential hazards before operating the equipment.
The information and material listed above along with this Operator’s Manual can assist you in meeting the OSHA
requirement for Operator annual training.
OSHA TRAINING REQUIREMENTS
The following training requirements have been taken from Title 29, Code of Federal Regulations Part
1928.57 (a)(6). www.osha.gov
Operator Instructions. At the time of initial assignment and at least annually thereafter, the employer shall instruct
every employee who operates an agricultural tractor or implement in the safe operating practices and servicing of

•

IMPLEMENTS: I have explained that Deflectors, Chain Guards, or Solid Skirts must be installed and
maintained in good repair.

•

DRIVELINES: I have made certain that all driveline, gearbox, and other shields are in good repair and fastened
securely in place to prevent injuries from entanglement or thrown objects.

•

HYDRAULIC MACHINES: I have explained the necessity of using clean hydraulic oil, changing filters as
instructed, stopping leaks, damage caused by operating with over-heated oil, caring for hoses, using hoses of
proper rating, maintaining the specified operating pressure and the potential hazard of oil’s penetrating the
skin.

•

FOLDING-TYPE IMPLEMENTS: I have explained that it is not possible to guard against thrown objects when
the head is lifted off ground and that operator is responsible to watch out for persons in the area. I have
explained that the lifted mower head or boom can contact overhead obstructions with damage to cables and

elements have stopped.
•

STOP, LOOK and LISTEN before approaching the mower to make sure all rotating motion has stopped.

•

ROTATING COMPONENTS CONTINUE to ROTATE after the PTO is shut off.

PTO SHIELDING:
TO AVOID SERIOUS INJURY OR DEATH FROM ENTANGLEMENT WHEN OPERATING IMPLEMENT:
•

KEEP PTO shields, integral driveline shields and input shields installed

•

DO NOT OPERATE mower without shields and guards in place or missing

•

REPAIR OR REPLACE if damage, broken or missing

•

ALWAYS REPLACE GUARDS that have been removed for service or maintenance.

•

Do Not use PTO or PTO guard as a step.

TO AVOID broken driveline during operations:
•

CHECK driveline for proper length between PTO shaft and implement gearbox shaft.(Refer to Instructions in
Operation Section)

•

Drivelines too short can pull apart or disengage.

•

Drivelines too long can bottom out.

Bottoming driveline telescoping assembly will stop sliding and become solid.
•

Driveline bottoming can push through support bearings and break off PTO shaft

•

AVOID sharp turns or lift mower to heights to cause driveline "knocking".

•

Lubricate driveshaft-telescoping components weekly.

CONTACT DEALER if implement driveline does not match Tractor PTO shaft:
•

DO NOT USE PTO ADAPTER.

Using a PTO adapter can cause excessive vibration, thrown objects, blade and implement failures by
doubling operating speed. Increased working length exposing unshielded driveline areas. PN PE01

machine and work area.
Know where fire extinguishers are kept—how
they operate—and what type of fire they are for.
Check readiness of fire extinguishers according to
manufacturer’s instructions. Make sure each tractor is
equipped with a fire extinguisher.

No Smoking
and No Open
Flames

Check for fuel, oil or hydraulic fluid leaks. Repair the
leaks and clean the machine before you operate it.
Ether/cold start fluid is flammable. Do not smoke
when using ether/cold start fluid. Always follow the
instructions on the can and in the manufacturer’s
operator’s manual(s) for your mower. Do not use ether/
cold start fluid if the engine is equipped with a glow plug
or other type of preheater.

As Needed

Follow A Safety Program
Be Alert!

For Safe Operation

Know where to get assistance. Know how to use a first
aid kit and fire extinguisher/fire suppression system.

You must be a qualified and authorized operator for
proper operation of your machine. You must clearly
understand the written instructions supplied by the
manufacturer, be trained—including actual operation of
the mower—and know the safety rules and regulations
for the worksite. It is a good safety practice to point
out and explain safety signs and practices and ensure
others understand the importance of following these
instructions.

Be Aware!
Take advantage of training programs offered.

Be Careful!
Human error is caused by many factors: carelessness,
fatigue, overload, preoccupation, unfamiliarity of operator
with the machine, drugs, and alcohol to name a few.
Damage to the tractor or mower can be fixed in a short
period of time, but injury, or death, has a lasting effect.
For your safety and the safety of others, encourage your
fellow workers to act safely.

Never Use Drugs
or Alcohol While
Operating

WARNING! Drugs and alcohol affect an operator’s
alertness and coordination and the operator’s ability
to safely operate the equipment. Never use drugs or
alcohol while operating the mowing equipment.
Never knowingly allow anyone to operate this
machine when their alertness or coordination is
impaired. An operator taking prescription or over-thecounter medication must consult a medical professional
regarding any side effects of the medication that would
hinder their ability to safely operate this equipment.

Follow A Safety Program
Know The Rules
Most employers have rules governing operation and
maintenance of equipment. Before you start work at a
new location, check with your supervisor or the safety
coordinator. Ask about the rules you will be expected
to obey.
The Occupational Safety and Health Administration
(OSHA) enforces federal laws within the United
States that apply to safe operation, application and
maintenance of equipment on a worksite. It is the
employer’s responsibility to comply with these laws.
An OSHA representative may periodically inspect a
worksite to see that these laws are being followed.
There may also be local or state/provincial laws or
international regulations that apply to this equipment

objects or blade contact:
— Keep chain shields, flexible or solid deflector shields
or discharge chutes in place and in good repair.
— Keep bystanders at least 300 ft (92 m) from mowing
operation.
— Never direct mower discharge toward anyone.
— Keep hands, feet and other body parts away from
rotating parts, blades and discharge openings.
— Do not operate mower in transport position.
Do not approach a mower until all motion has stopped.
Mower PTO drive engagement:

Rotating Blades –
Keep Away

Do Not Operate a
Damaged Mower

Mower-Thrown Objects
Depending on the designed purpose, mowers are
designed to cut grass, weeds, brush and crops. The
mower blades have been designed and tested for
rugged use. The mower blades, however, are not
intended to contact solid objects like rocks, concrete
or metal. Such impact can cause broken objects to be
thrown up to 300 ft (92 m). Bystanders should never
be within 300 ft (92 m) of an operating rotary mower or
within 100 ft (30 M) of a properly equipped disc mower.

Operate Safely
Mower shielding is designed to reduce the risk of thrown
objects and must be properly maintained and in place
during mowing operations.
The risk of serious injury or death from thrown objects
can be significantly reduced by following three rules.
If all of these safety rules are not followed, the
mowing operation must be stopped if anyone comes
within the safety limit for the mower type.
First — Inspect the area prior to mowing and remove
stones, branches, wire, cable, metal, glass and other
solid objects before operating. Any objects that cannot
be removed must be clearly marked and carefully
avoided by the operator.
In non-crop areas with grass and weeds high enough to
hide objects that could be struck by the blades, inspect
the area and remove or mark large debris or obstacles.

Follow
All Mower
Safety Rules

Second — Mower-thrown object shielding must be
used when operating near roads, parks, populated
areas or other areas where thrown objects could
injure bystanders or damage property. Follow the
manufacturer's operator's manual.
Third — Cross diagonally when mowing through
ditches, sharp dips, and drops. Raise the mower to
prevent the mower blades from hitting the ground.

Mow the area at an intermediate height. Inspect the area
closely and remove or mark any remaining debris or
obstacles. Mow again at desired final height.

Operate Safely
Mower-Thrown Objects (continued)
Disc Mowers — When using a disc mower it is
important to know the area to be mowed. If the operator
has mowed the field before and is familiar with all
obstacles that may be present, it is sufficient to watch
ahead of the mower path for any additional objects that
may have entered the field. Be ready to stop or avoid
any objects that could be hazardous if thrown by the
mower. If you plan to mow an unfamiliar field and it is
next to a traveled road or people may be within 100
ft (30 m) of the mower you must inspect, and clean or
mark the field.

Do Not Mow
in Reverse

Use Proper
Ground Speed

Mowing Ground Speed
Mowing In Reverse
Do not mow while traveling in reverse. Objects are more
likely to be thrown and can travel further.
Shut off the PTO, wait for the blades to stop turning,
raise the mower, and then back up.
Mow traveling in the forward direction.

Proper ground speed depends on terrain conditions and
grass type, density and height to be cut:
— Normal ground speed range is 2 to 5 mph.
— Use slower ground speed for mowing tall, dense grass.
— Use faster ground speed for mowing medium height,
thin grass and under smooth terrain conditions.
— Use slower ground speed for mowing in rough,
sloping or unfamiliar terrain.
Disc mowers are designed to use faster ground speeds
for operating in fields clear of debris and surface hazards.

Operate Safely
Extremely Tall Grass Mowing
You may need to mow extremely tall, non-crop grass
twice. (See page 13, Mower-Thrown Objects.)
First mowing pass:
— Shut the mower and tractor down using proper
equipment shut down practice before dismounting
tractor. (See page 18, Proper Equipment Shut Down
Practices.)
— Inspect the area and remove or mark debris and
obstacles.
— Cut grass higher (10-15 inches) to avoid hidden objects.
Second mowing pass:
— Shut the mower and tractor down using proper
equipment shut down practice before dismounting
tractor.
— Inspect the area and remove or mark debris and
obstacles.
— Cut grass at desired height and, when possible,
90 degrees to the first mowing pass.

Stop Blade
Before
Unclogging

Provide Adequate
Clearance for
Mower Swing

Watch Equipment Clearances
Three-point hitch and side-mounted mowers have a
larger turning arc than pull-type mowers. Allow sufficient
clearance for mower swing while turning.
Do not allow bystanders near the tractor and mower
when moving or transporting the tractor and mower.

Operate Safely
Under Mount Mower Safety Practices
When mowing with an under mount mower:
— Keep removable discharge chute in place and over
discharge opening.
— Never stand on a mower housing when the tractor
engine is operating.
— Distribute grass clippings with discharge chute facing
mowed area.
— Before clearing a clogged mower or discharge
chute, shut down your machine using proper
equipment shut down practice. (See page 18, Proper
Equipment Shut Down Practices.)

Overhead Obstruction Hazards And Risks
Check for overhead obstructions with raised wing
or boom mowers to avoid serious injury or death by
contact with:
— Electrical power lines and apparatus.
— Low tree limbs.
— Other overhead obstructions.
— Maintain specified distance from power lines and
apparatus. Never approach energized power lines or
apparatus with any part of your machine unless all
local, state/provincial and federal (OSHA) required
safety precautions have been taken. Use extreme
caution.

Do Not

power lines or apparatus. Do not allow the machine or
attachment to approach or contact any power line.
Do not approach or touch any machine in contact
with a power line.

Operate Safely
Wing And Side Mount Mowers Safety Practices
Raised wing positions reduce shielding protection and
increases the thrown object and blade contact hazard
risks.
Avoid possible serious injury or death by thrown
objects or blade contact from raising and lowering
wings during mowing operations:
— Do not mow with bystanders within 300 ft (92 m) of
the mower.
— Be sure no one is near mower while raising or
lowering wings.
— Shut off the PTO and wait for all rotating elements to
stop before raising the mower deck or wing section.
— Only raise wing to clear objects in the mowing path
or to match ground slope.
— Lower raised wing to ground after clearing object or
ground slope conditions.
— Stop mowing if anyone approaches within 300 ft
(92 m) of mowing area.

Avoid Hitting
Obstructions

Ditch Bank Mowing Safety Practices
Use extreme care when mowing ditch banks. Watch for
washouts, eroded areas and mowing obstructions along
the ditch banks. Hitting obstructions with side-mount
or boom mowers may swerve the tractor’s front end
toward the ditch.

Operate Safely
Raised wing and boom mower ditch bank operations may
reduce the mower’s thrown object shielding effectiveness
for the mower operator’s protection.
— Use enclosed ROPS cabs, special protective
enclosures and other operator shielding available from
the manufacturer when performing these operations.
— Inspect mowing area and remove or mark all foreign
objects and debris to be avoided by mower.

Use
Enclosed ROPS
Cabs or Protective
Enclosures

Uneven Terrain Mowing Safety Practices
Tractor and mower stability is reduced on slopes and
uneven terrain.
As in all conditions when mowing, use tractors
equipped with ROPS and seat belt. Make sure the
ROPS are raised and locked in place and always
wear your seat belt.
Prevent tractor and mower overturns and maintain
equipment stability control:
— Review tractor and mower operator’s manuals for
operating safety practices on slopes and uneven
terrain conditions. Explain the practices to those
users and operators who cannot read.
— Avoid extremely steep slope operations.

handling wooden blocks or sharp-edged metal.

Clean
Slippery Surfaces

Always use safety glasses, goggles or a face shield. They
provide eye protection from fluids under pressure, during
grinding and while servicing batteries. Protection is also
needed from flying debris, liquids and loose material
produced by equipment, tools and pressurized air/water.
Wear a face shield and follow manufacturer's instuctions
when you disassemble spring-loaded components or work
with battery acids. Wear a welding helmet or goggles with
a shaded filter when you weld or cut with a torch.
Do not sand, grind, flame-cut, braze or weld without a
NIOSH-approved respirator or appropriate ventilation.
If welding is required on this machine, refer to the
manufacturer’s operator's or service manuals or consult
your equipment dealer for proper procedures.
Keep pockets free of all objects that could fall out—and
drop into machinery.
Handle tools and heavy parts sensibly—with regard
for yourself and other persons. Lower items—don’t
drop them.

Hydraulic System Hazards
The hydraulic system is under pressure whenever the
engine is operating and may hold pressure even after the
engine is shut off. Cycle all hydraulic controls including
the auxiliary hydraulic control after the engine is shut
down. Relieve trapped pressure in the lines after the
attachments are shut down and resting on the ground.
During inspection of the hydraulic system:
— Wait for fluid to cool before disconnecting the lines.
Hot hydraulic fluid can cause SEVERE BURNS.
— Do not use your hand to check for leaks. Instead,
use a piece of cardboard or paper to search for leaks.
— Wear appropriate eye protection. Hydraulic fluid can
cause permanent eye injury.
WARNING! Hydraulic fluid under pressure can penetrate
the skin or eyes and cause serious injury, blindness or
death. Fluid leaks under pressure may not be visible.
Use a piece of cardboard or wood to ﬁnd leaks, not
your hand. Wear a face shield or safety goggles for
eye protection. If fluid is injected into the skin, it must
be removed within a few hours by medical personnel
familiar with this type of injury.

Tire And Wheel Maintenance
Check your tires and wheels daily because the stability
of the tractor and mower can be dramatically affected
by tire pressure or damage to tires or wheels.
Check tires for:
— Correct pressure.
— Cuts and bulges.
— Nails or other punctures.
— Uneven or excessive wear.
— Condition of valve stems and caps.
Check wheels for:
— Damage to the rims.
— Missing or loose lug nuts or bolts.
— Misalignment.
All tire service should be performed by a qualified tire
service center or by an authorized service person who
has been properly trained in the procedures and use of
safety equipment designed for tire servicing.

Proper Tire
Pressure

Perform Maintenance Safely
Tire And Wheel Maintenance (continued)
WARNING! The types of wheels and tires usually
found on this equipment require special care when
servicing to prevent death or serious injury.
Do not inflate the tires above the recommended
pressure. Be sure to replace tire ballast if equipped. See
manufacturer’s specifications for ballast requirements.
Keep wheel lug nuts tightened to manufacturer’s
recommendations.

Never cut or weld on a wheel with an inflated
tire mounted on it. This could cause explosive
decompression.
Check that the tire size and wheel are correctly matched.
When replacing the tires, ensure the tires are of the
appropriate rating specified by the manufacturer.
Tires should not be operated at speeds higher than their
rated speed. Most agricultural tires are rated for 20mph
maximum speed.

A rise in tire pressure during operation is normal, and
should NOT be reduced.
Never reinflate a tire that has been run flat or seriously
underinflated without removing the tire from the wheel.
Have the tire and wheel closely inspected for damage
before remounting.

Avoid
Tire Explosion

When adding air to a tire, do so from a distance. Use
a long hose with self-attaching chuck. Always stand
behind tread when adjusting tire pressure.
Do not inflate tires with flammable gases or from
systems using an alcohol injector.

Perform Maintenance Safely
Complete Service And Repairs Before Machine
Is Released
Tighten all bolts, fittings, and connections to torques
specified by the manufacturer.

Verify
Service Work
When
Completed

Install all guards, covers, and shields after servicing.
Replace or repair any damaged parts. Refill and
recharge pressure systems only with manufacturer
approved or recommended fluids.
Start the engine and check for leaks. (See page 23,
Hydraulic System Hazards.) Operate all controls
to make sure the tractor and mower are functioning
properly. Test the machine if necessary. After testing,
shut down and check the work you performed. Are
there any missing cotter pins, washers, locknuts, etc.?
Recheck all fluid levels before releasing the equipment
for operation.
All parts should be inspected during repair and replaced
if worn, cracked or damaged. Excessively worn or
damaged parts can fail and cause injury or death.

Mower Blade Maintenance
Do not take chances using damaged or bent blades.
The mower manufacturers from the Association
of Equipment Manufacturers (AEM) and the Farm
Equipment Manufacturers Association (FEMA) advocate
that you DO NOT reuse, straighten, hard face or weld
mower blades. Death or serious injury could result if a
broken blade is thrown from a mower.

Replace any damaged or illegible safety signs.

Perform Maintenance Safely
Mower Blade Maintenance (continued)
— How are mower blades made?
Mower blades are made of high strength alloy spring
steel. They are hot-forged and shaped to meet the
manufacturer’s individual specifications, then heat
treated and tempered to a high strength, ductile state
to reduce the possibility of breaking while mowing.
Blades are tested to ensure they meet strength,
hardness, and ductility standards. If a blade fails to
meet any of these specifications, it will not be used
on the mower.
— What happens when a mower blade bends?
It takes a great amount of impact force to bend
the blade. This impact force often results in the
blades being gouged or chipped. After a blade
is damaged by a gouge or chip a blade failure is
much more likely to occur. When a blade is severely
bent, a microscopic crack may be created in the
blade. Straightening the blade does not remove or
repair this crack, but may cause additional cracks.
Additional stresses during mowing operations can
result in an unexpected blade failure.

— Avoid bending blades. Help prevent mower blades
from bending or cracking by avoiding contact with
solid objects. Mower blades are intended to cut
grass, shrubs, woody vegetation, and small trees and
limbs. They are not intended to contact solid objects
such as rocks, concrete, or steel posts. Inspect the
area prior to mowing. Remove or clearly mark any
solid objects and mow around them.
— Replace damaged blades! Inspect the mower blade(s)
daily or after hitting any solid object. If a mower blade
becomes damaged (bent, gouged, cracked) or worn
more than 25 percent of the original size, it should
be removed and replaced with a new blade. Always
use the original manufacturer’s blades. Aftermarket
brand blades may not meet the mower manufacturer’s
strength, hardness and ductility requirements.
— Do not take chances mowing with damaged or
bent blades. Using a damaged or straightened
mower blade can result in the blade breaking and
being thrown into the operator or a bystander causing
death or serious injury. The price of a new blade is
small compared to the potential for the serious injury
that could result from a bent or broken blade being
thrown from the mower.

Final Word To The User

Objetos arrojados por la cortadora de césped
Dependiendo del propósito previsto, las cortadoras
están diseñadas para cortar hierba, maleza, broza y
cultivos. Las hojas de la cortadora están diseñadas y
probadas para uso intensivo. Las hojas de la cortadora,
sin embargo, no están diseñadas para entrar en contacto
con objetos sólidos como rocas, cemento o metales. Un
impacto de este tipo puede arrojar objetos rotos hasta
300 pies (92 m) de distancia. Nunca debe haber personas
ajenas a menos de 300 pies (92 m) de una cortadora
giratoria en funcionamiento o a menos de 100 pies (30 m)
de una cortadora de disco correctamente equipada.

Operación con seguridad
Los escudos de la cortadora están diseñados para reducir
el riesgo de objetos arrojados y se deben mantener
correctamente y en su lugar durante las operaciones de
corte.

Siga todas
las reglas de
seguridad

El riesgo de lesiones graves o muerte puede reducirse
significativamente si se siguen estas reglas. Si no se
siguen todas estas reglas de seguridad, la operación
de corte debe detenerse en caso de que alguna
persona ingrese dentro del límite de seguridad
correspondiente a cada tipo de cortadora.

Realice el corte de la zona a una altura intermedia.
Inspeccione la zona atentamente y retire o marque
cualquier residuo u obstáculo restante. Corte nuevamente
a la altura final deseada.

Primero — Inspeccione la zona antes de cortar y retire las
piedras, ramas, alambres, cables, metales, vidrios y otros
objetos sólidos antes de hacer funcionar la máquina. Los
objetos que no puedan retirarse deben marcarse con
claridad y ser evitados con cuidado por el operador.

Segundo — Los escudos para objetos arrojados por la
cortadora deben usarse cuando se opera cerca de caminos,
parques, zonas pobladas u otras zonas donde objetos
arrojados podrían lesionar a personas ajenas o dañar la
propiedad. Siga el manual del operador del fabricante.

En áreas sin cultivos con hierba y maleza de altura
suficiente como para ocultar objetos que podrían ser
golpeados por las hojas, inspeccione la zona y retire o
marque los residuos u obstáculos grandes.

Tercero — Cruce en sentido diagonal cuando realiza
el corte a través de zanjas, depresiones marcadas y
hundimientos. Eleve la cortadora para evitar que las hojas
de la cortadora golpeen el suelo.
13

Operación con seguridad
Objetos arrojados por la cortadora de césped
(continuación)

Apague la TDF, espere que las hojas dejen de girar, eleve
la cortadora y, después, retroceda.

Cortadoras de disco — Cuando se usa una cortadora
de disco, es importante conocer la zona donde se va a
cortar. Si el operador ha realizado cortes en el terreno
antes y está familiarizado con todos los obstáculos
que puede haber, es suficiente observar delante de la
trayectoria de la cortadora para detectar cualquier objeto
adicional que pueda haber ingresado en el terreno. Esté
preparado para detenerse o evitar objetos que podrían
ser peligrosos si son arrojados por la cortadora. Si piensa
cortar en un terreno que no conoce bien y se encuentra
junto a un camino transitado o puede haber personas
a menos de 100 pies (30 m) de la cortadora de césped,
debe inspeccionar y limpiar o marcar el terreno.

Corte desplazándose en sentido de avance.

Cómo cortar en retroceso
No corte mientras se desplaza en retroceso. Es más
probable que se arrojen objetos y que éstos puedan llegar
más lejos.

No corte
en retroceso

Use la velocidad
de desplazamiento
correcta

Velocidad de desplazamiento durante el corte
La velocidad de desplazamiento correcta depende de las
condiciones del terreno y del tipo de hierba, la densidad y
la altura que debe cortarse:
— El rango normal de velocidad de desplazamiento es de
2 a 5 mph (3.2 a 8 km/h).
— Use una velocidad de desplazamiento menor para
cortar hierbas altas y densas.
— Use una velocidad de desplazamiento mayor para
cortar hierba delgada a altura media y con condiciones
de terreno sin dificultades.
— Use una velocidad de desplazamiento menor par acortar
en terreno irregular, con pendientes o no muy conocido.
Las cortadoras de disco están diseñadas para usar
velocidades de desplazamiento mayores cuando funcionan
en terrenos despejados de residuos y peligros superficiales.

Operación con seguridad
Corte de hierba extremadamente alta
Puede ser necesario cortar dos veces la hierba
extremadamente alta que no sea cultivo. (Consulte la página
13, Objetos arrojados por la cortadora de césped.)

Detenga
la hoja antes de

Primera pasada de corte:
— Apague la cortadora y el tractor usando la práctica
correcta de apagado de equipos antes de descender del
tractor. (Consulte la página 18, Prácticas correctas de
apagado de los equipos.)
— Inspeccione la zona y retire o marque cualquier residuo u
obstáculo.
— Corte la hierba a mayor altura (10 a 15 pulg. [25 a 38 cm])
para evitar los objetos ocultos.

Proporcione el
espacio libre
adecuado para la
oscilación de la
cortadora de césped

Segunda pasada de corte:
— Apague la cortadora y el tractor usando la práctica
correcta de apagado de equipos antes de descender
del tractor.
— Inspeccione la zona y retire o marque cualquier residuo
u obstáculo.
— Corte la hierba a la altura deseada y, de ser posible, a
90 grados con respecto a la primera pasada de corte.
14

Preste atención a los espacios libres de los
equipos
Las cortadoras con enganche de tres puntos y montaje
lateral tienen un arco de giro mayor que las tipo de tiro.
Deje el espacio libre suficiente para la oscilación de la
cortadora cuando gira.
No permita que haya personas ajenas cerca del tractor
y la cortadora de césped cuando mueve o transporta el
tractor y la cortadora.

Operación con seguridad
Prácticas de seguridad para la cortadora de
césped de montaje inferior
Cuando se traslada con una cortadora de césped de
montaje inferior:
— Mantenga la rampa de descarga extraíble en su lugar y
por encima de la abertura de descarga.
— Nunca se pare sobre la carcasa de una cortadora
de césped cuando el motor del tractor está en

Operación con seguridad
Prácticas de seguridad para cortadoras de
césped con laterales y montaje lateral

300 ft
(92 m)

Las posiciones elevadas de los laterales reducen la
protección de los escudos y aumentan los riesgos de
objetos arrojados y contacto con las hojas.
Evite la posibilidad de lesiones graves o muerte por
objetos arrojados o contacto con las hojas causados
por la elevación y el descenso de los laterales durante
las operaciones de corte:
— No realice cortes con personas ajenas presentes a
menos de 300 pies (92 m) de la cortadora de césped.
— Asegúrese de que no haya personas cerca de la
cortadora mientras se elevan o descienden los
laterales.
— Apague la TDF y espere hasta que todos los elementos
giratorios se hayan detenido antes de elevar la
plataforma o la sección lateral de la cortadora.
— Únicamente eleve el lateral para quitar objetos de la
trayectoria de corte o para acompañar una pendiente
del terreno.
— Descienda hasta el suelo el lateral elevado una vez que
se eliminó el objeto o se superó la pendiente.
— Detenga el trabajo de corte si alguna persona se acerca
a menos de 300 pies (92 m) de la zona de corte.

Mantenga a las
personas ajenas
alejadas de la zona
de corte

Evite golpear
obstrucciones

Prácticas de seguridad para trabajos de corte en
orillas de zanjas
Use extremo cuidado al realizar cortes en orillas
de zanjas. Preste atención a escurrimientos, zonas
erosionadas y obstrucciones para el corte a lo largo de
las orillas de zanjas. Si se golpean obstrucciones con
cortadoras de montaje lateral o con aguilón, el extremo
delantero del tractor puede desviarse hacia la zanja.

Operación con seguridad
Los trabajos en orillas de zanjas con aguilón y lateral
elevado pueden reducir la eficacia de la protección del
operador de la cortadora que proporcionan los escudos
para objetos arrojados.

Utilice cabinas
cerradas con ROPS
o cerramientos de
protección

— Cuando realice estas operaciones, use cabinas cerradas
con ROPS, cerramientos protectores especiales y otros
escudos para el operador que ofrece el fabricante.
— Inspeccione la zona de corte y retire o marque todos
los objetos extraños y los residuos que deberá esquivar
la cortadora.

de que el ROPS está elevado y trabado en su lugar y
use siempre el cinturón de seguridad.
Prevenga los vuelcos del tractor y de la cortadora de césped
y mantenga controlada la estabilidad de los equipos:
— Repase los manuales del operador del tractor y de la
cortadora para ver las prácticas de seguridad para
operaciones en pendientes y terrenos desparejos.
Explique las prácticas a los operadores que no puedan
leerlas.
— Evite trabajar en pendientes extremadamente
empinadas.

Realización de mantenimiento con seguridad
Mantenimiento de neumáticos y ruedas
(continuación)
¡ADVERTENCIA! Los tipos de ruedas y neumáticos
que generalmente se encuentran en estos equipos
requieren cuidados especiales al realizar servicios
para evitar lesiones graves o la muerte.
No infle los neumáticos por encima de la presión
recomendada. Asegúrese de volver a colocar el lastre
de los neumáticos si está instalado. Consulte las
especificaciones del fabricante para ver los requisitos
de lastre.
Mantenga las tuercas de las ruedas apretadas según las
recomendaciones del fabricante.
Es normal que la presión de los neumáticos aumente
durante el funcionamiento; NO se debe reducir.
Nunca vuelva a inflar un neumático que se ha desinflado
mucho o por completo sin retirar el neumático de la
rueda. Haga inspeccionar atentamente el neumático y la
rueda para detectar daños antes de volverlos a armar.
Al agregar aire a un neumático, hágalo desde cierta
distancia. Use una manguera larga con mandril de
autofijación. Siempre párese detrás de la trocha cuando
ajusta la presión de un neumático.

Evite la explosión
de los neumáticos

No infle neumáticos con gases inflamables o con sistemas
que usan un inyector de alcohol.
Nunca corte o suelde una rueda con un neumático inflado
instalado en ella. Esto podría causar descompresión
explosiva.
Verifique que el tamaño del neumático y la rueda
coincidan correctamente.
Cuando reemplaza neumáticos, asegúrese de que sean de
la clasificación adecuada especificada por el fabricante.
Los neumáticos no deben funcionar a velocidades más
altas que las nominales. La mayoría de los neumáticos
para agricultura están clasificados para una velocidad
máxima de 20 mph (32 km/h).

Realización de mantenimiento con seguridad
Servicio y reparaciones completas antes de
liberar la máquina
Apriete todos los pernos, accesorios y conexiones con las
torsiones especificadas por el fabricante.

Veriﬁque el trabajo
de servicio cuando
está completo

Instale todas las guardas, cubiertas y escudos después
de realizar los servicios. Reemplace o repare los que
estén dañados. Llene y recargue los sistemas a presión
sólo con los fluidos aprobados o recomendados por el
fabricante.
Arranque el motor y revise para detectar fugas. (Consulte
la página 23, Riesgos del sistema hidráulico.) Haga
funcionar todos los controles para asegurarse de que el
tractor y la cortadora de césped funcionan correctamente.
Pruebe la máquina si es necesario. Después de las
pruebas, apague y verifique el trabajo realizado. ¿Falta
algún pasador, arandela, tuerca de seguridad, etc.?
Vuelva a revisar todos los niveles de fluidos antes de
liberar la máquina para el funcionamiento.
Todas las piezas deben ser inspeccionadas durante la
reparación y deben reemplazarse si están gastadas,
rajadas o dañadas. Las piezas excesivamente gastadas o
dañadas pueden fallar y causar lesiones o la muerte.

Mantenimiento de las hojas de la cortadora
No corra riesgos usando hojas dañadas o dobladas. Los
fabricantes de cortadoras de césped de la Asociación
de Fabricantes de Equipos (Association of Equipment
Manufacturers, AEM) y la Asociación de Fabricantes de
Equipos para Agricultura (Farm Equipment Manufacturers
Association, FEMA) piden que las hojas de cortadoras
NO se reutilicen, enderecen, refuercen en su superficie o
suelden. Si una hoja rota es arrojada por una cortadora,
podrían producirse lesiones graves o la muerte.

Reemplace cualquier letrero dañado o ilegible.

Realización de mantenimiento con seguridad
Mantenimiento de las hojas de la cortadora
(continuación)
— ¿Cómo están hechas las hojas de la cortadora
de césped? Están hechas acero para resortes de
aleación de alta resistencia. Se forjan en caliente y se
les da forma para cumplir con las especificaciones
individuales del fabricante; luego, se tratan y templan
a un estado dúctil, de alta resistencia para reducir la
posibilidad de rupturas durante el corte. Las hojas se
prueban para garantizar que cumplan con las normas
de resistencia, dureza y ductilidad. Si una hoja no
cumple con alguna de estas especificaciones, no se
utilizará en la cortadora de césped.
— ¿Qué sucede cuando se dobla una hoja de la
cortadora? Se necesita una gran fuerza de impacto
para doblar la hoja. Esta fuerza de impacto a menudo
resulta en que las hojas se agujerean o marcan. Una
vez que una hoja está dañada por un agujero o una
marca, es mucho más probable que ocurra una falla
de la hoja. Cuando una hoja está gravemente doblada,
puede crearse una rajadura microscópica en ella.
Enderezar la hoja no quita o repara esta rajadura, sino
que puede causar rajaduras adicionales.Tensiones
adicionales durante los trabajos de corte pueden
resultar en una falla imprevista de la hoja.

— Evite doblar las hojas. Contribuya a prevenir que las
hojas de la cortadora se doblen o rajen evitando el
contacto con objetos sólidos. Las hojas de la cortadora
de césped están destinadas a cortar hierba, arbustos,
vegetación leñosa y árboles y ramas pequeños. No
están diseñadas para entrar en contacto con objetos
sólidos como roca, cemento o postes de acero.
Inspeccione la zona antes de usar la cortadora. Retire
o marque claramente los objetos sólidos y corte
alrededor de ellos.
— Sustituya las hojas dañadas! Inspeccione las hojas
de la cortadora diariamente o después de golpear
algún objeto sólido. Si una hoja de la cortadora de
césped se daña (está doblada, agujereada, rajada) o
desgasta más del 25 por ciento del tamaño original,
debe retirarse y sustituirse con una nueva. Siempre use
las hojas originales del fabricante. Las hojas de marcas
no originales pueden no cumplir con los requisitos de
resistencia, dureza y ductilidad del fabricante de la
cortadora.
— No corra riesgos usando hojas dañadas o dobladas.
El uso de una hoja de cortadora dañada o enderezada
puede resultar en la ruptura de la hoja y que la hoja
sea arrojada hacia el operador o una persona ajena
causando una lesión grave o la muerte. El precio
de una nueva hoja es bajo en comparación con la
posibilidad de una lesión grave que podría resultar de
una hoja doblada o rota arrojada por la cortadora

Assembly Section 3-2

ASSEMBLY
TRACTOR PREPARATION
Installing the Operator Guard - Cab Tractor
Rhino strongly recommends installing the 1900 Boom Mower on a cab tractor equipped with impact resistant
glass windows. In addition, the Rhino 1900 Boom Mower includes an operator guard kit which must be
installed on the tractor before using the mower.

ASSEMBLY
The guard kit consists of two areas of wire mesh which can be shaped to match your cab windows. Secure the
upper edge of the mesh to the rear window cab gutter and the RH side window cab gutter. Secure the lower
edge of the mesh using the spring loaded hooks as shown in the diagram above. Since tractor cabs can vary in
size and shape, it may be necessary to modify the supplied clips or make brackets to secure the mesh.
Ballast
When attaching a boom mower to a tractor, it is extremely important to make the total unit as stable as
possible. Adding Ballast or weights to the tractor may be necessary to achieve the guidelines shown below.
Front Axle: Front tractor weights may be necessary to put 20% of the total unit weight on the front axle. (Total
unit weight is the sum of the tractor weight and the mower weight.) This amount will improve stability when
driving the tractor.
Rear Axle: Wheel weights or liquid ballast should be added to the Left Hand rear tire and wheel so that a
minimum of 1500lbs of the rear axle weight is on the Left Hand side when the mower boom and head are in a
normal “off the ground” operating position. (For Example, the operating position for hedge cutting.)
A wide range of factors can affect the stability of the tractor and boom mower, and all should be considered
before operating the unit
Factors that affect stability:
•
•
•
•
•

Center of gravity of the tractor and boom mower combined.
Position of the boom and cutting head.
Weight, wheel width, and wheelbase of the tractor.
Acceleration, braking, turning, and the relative position of the cutting head.
Ground conditions, including slope and softness of the ground.

Suggestions to improve stability:
•
•

Increase the wheel width of the rear wheels: a tractor with wider wheels is more stable.
Ballast the Left Hand rear wheel. Liquid can be added to about 75% of the tire volume. See your tractor
dealer or tire supplier for recommendations on the type of liquid.
• Addition of wheel weight to the Left Hand rear wheel.
These factors and suggestions are not all inclusive and should be used as a general guideline for tractor
stability only, For additional information, and for information on your tractor’s strength, see your tractor dealer
or tire supplier.

ASSEMBLY

OIL REQUIREMENTS
Tank
Rear mounted hydraulic pumps are attached directly to the tractor PTO and will be operating when the tractor
engine is running. Never start a tractor with a rear mounted pump attached without first filling the hydraulic tank
with the correct hydraulic oil. Rhino specifies hydraulic oil based on ambient operating temperature ranges as
prescribed in iso standards. The most common oil used in Rhino mowers is the AW ISO VG 100 Oil. The
vg100 oil has the most optimal operating temperature range in regard to ambient temperatures but will also
survive as mower component temperatures rise. It is no uncommon to see oil temperatures exceeding 200º in
the summer time. In addition, a good quality vg100 oil will provide sufficient lubrication in cold temperatures to
allow low idle warm up of the machine to enable operation within the temperature range specified. Hydraulic oil
must be filtered prior to installing it the hydraulic tank of the mower. Fill reservoir to approximately 2” below the
top of the tank. The capacity is approximately 200 liters (44 gallons). Do not overfill the tank.

FITTING CONTROL UNIT IN CAB
CABLE CONTROLLED MODELS
The control unit is bolted to a mounting bracket.
This bracket may be bolted to the mud wing or cab cladding in a convenient location ensuring that no structural
member of the cab or roll bar is drilled.
In deciding the final position of the control box remember not to exceed the minimum acceptable bend -radii of
8"' for the cables.
The control lever for the cable operated rotor control valve is mounted in a similar fashion adopting the same
precautions pertaining to drilling and cable runs.

RUNNING UP PROCEDURE
1. Ensure P.T.O. lever is in neutral position, and isolate tractor hydraulic linkage. Start tractor and select
external service supply. Allow the tractor to run for several minutes before attempting to operate any of the
machine control levers.
2. On operating move the levers through their complete range ensuring that all movements are functioning
correctly.
3. Check the tractor rear axle oil level and top up if necessary.
4. Place the flail head at a safe attitude and bring tractor engine revolutions to 1000 rpm. Engage P.T.O. and
allow the rotor to run for several minutes. Do not leave the tractor cab or allow anyone to approach the flail
head at this time.
Do not allow the pump to continue working if the rotor does not turn. Overheating and
serious pump damage to the pump can be caused in a very short time.
5.After running up the machine, increase PTO speed to approximately 360 RPM. Run
machine further for five minutes before disengaging the PTO and stopping tractor. The reason for this
running period under a no load condition is to thoroughly circulate the oil in the reservoir through the return
line filter.
6. Check the hose runs and observe that they are free from any pinching, chafing, straining or kinks. Recheck
the oil level in the tank and top up as necessary.

REMOVAL FROM TRACTOR
Read carefully before commencing to remove the machine from the tractor.
The order of the following steps must be followed exactly. Disconnecting the top link must be the last operation
prior to driving the tractor away from the machine.
Do not operate valve lever or machine controls through the rear cab window while standing
on or among linkage components. Always seek assistance.
Select a firm level site for parking the machine.

OPERATION
3.2 Tractor Lighting and SMV Emblem

OPERATION

If the tractor will be operated near or traveled on a
public roadway it must be equipped with proper
warning lighting and a Slow Moving Vehicle (SMV)
emblem which are clearly visible from the rear of
the unit. Most tractor’s have different settings for
operating and transporting lighting. Refer to the
tractor operator’s manual for using the tractor’s
light switch and operating the turn signals.
OPS-B- 0017

3.3 Tractor Ballast
To ensure tractor stability when operating on flat surfaces the left rear tractor tire MUST exert a minimum
down force (weight) of 1500 lbs. on the ground when the tractor is on level ground, its boom is fully extended
and the mower head is horizontal and two feet above the ground. A tractor that does not meet this criteria is
DANGEROUS and should not be operated as upset of the unit can occur resulting in possible serious injury
and property damage.

If the unit is operated on slopes greater than 5,
additional counterweight will be required.
Operation of the unit on slopes greater than 11
percent (6.4 degrees) is not recommended under
any circumstances. On a tractor with a 96” outside
to outside tire spread, an 11 percent (6.4 degrees)
slope occurs when one rear tractor tire is about 8”
lower than the other rear tire. OPS-B- 0018_C

Operation Section 4-6

OPERATION
3.4 Tractor Safety Devices
If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with
proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of
the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor
warning signals are obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were
removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO
with the PTO master shield missing or in the raised position. OPS-U- 0004

The horsepower required to operate the mower depends on many factors including vegetation to be cut, terrain
condition, operator experience, and condition of the mower and tractor. For most mowing condition, the 1600
boom mower requires a tractor with at least 60 HP. Operating the mower with a tractor that does not have
adequate power may damage the tractor engine.

3.6 3-Point Hitch
1900 boom mowers can attach to tractors with a
CAT II hitch. Refer to the tractor operator’s manual
for the category of the tractor used. If the hitch
does not conform to ASAE Cat II dimensions, the
mower may not fit or raise properly. Consult an
authorized dealer for possible modification
procedures to mount nonconforming hitches.
Use the correct hitch pins for the hitch category
being used. For Cat II hitches it requires 1-1/8”
lower and 1” upper diameter hitch pins.

OPERATION
3.7 Hydraulics
The 1900 is available with a totally Independent hydraulic system complete with Rotor Rotation Control. The
rotor can be started, stopped, or reversed by operating a lever on the Control Console.

3.8 Front End Weight

OPERATION

A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end
weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the
front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front
weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005

3.9 Power Take Off (PTO)
Depending on the unit, the mower is designed to operate at a PTO speed of 540 RPM. Most tractors operate
at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and
tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those
operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft.
Note: Refer to the tractor owner’s manual for instructions to change PTO speeds on models that operate at
more than one speed.
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an
over-running clutch must be used between the PTO output shaft and the driveline of the mower. An
authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006_B

DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)

Never operate the Tractor and Mower if the Implement input driveline is directly connected
to the Tractor transmission. Tractor braking distances can be substantially increased by
the momentum of the rotating Mower blades driving the Tractor transmission even though
the Tractor clutch has been disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation. (S3PT-16)

4. GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the implement and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for
a complete explanation. OPS-U- 0007

Check the fluid level in the Hydraulic Tank on the Tractor, and add oil if required. As the air has been forced out
of the Cylinders and Hoses, it goes into the Hydraulic Tank and reduces the volume of oil. Maintain the oil level
within the sight gauge located on the side of the resevoir. Never fill the tank above the sight gauge to allow for
the expansion of the oil. The tank maintains pressure after the mower has been run. Stand off to one side
when removing the breather cap element to prevent possible injury. To relieve pressure remove the breather
cap element and depress the spring loaded pressure valve to release any excess air. OPS-B- 0024_H

Attention: Oil Filler Cap is also the Pressure Relief Cap.
Remove cap slowly to relieve pressure before removing cap completely. Stay clear to prevent being scalded with hot oil that may spray out of the tank that is still pressurized and may
cause serious injury to eyes, face, and exposed skin. (Ops-0001-MISC)

9. BREAKAWAY
The machine is fitted with a hydraulic breakaway device which protects the structure of the machine should an
unforeseen obstacle be encountered.
NOTE: The breakaway function does not relieve the operator of his responsibility to drive carefully, be alert and
AVOID OBVIOUS HAZARDS BEFORE CONTACT OCCURS.

NOTE: The force required to activate the breakaway system will vary dependent upon the gradient of work. It
will require less force when working uphill and vice versa.
With 'AUTO RESET' selected:
When the slew relief valve setting is exceeded oil is
displaced from the slew ram into the base of the lift ram
which causes the head to rise as the arm pivots
backwards to clear the obstruction. Resetting of the
head into the work position occurs automatically.
With 'SLEW' selected:
When the slew relief valve setting is exceeded oil is
displaced from the slew ram allowing the arm to pivot
backwards horizontally and the obstacle to be cleared.
Re-setting the head into the work position is carried out
manually by selecting 'SLEW OUT' on the control
assembly

1900 07/11
© 2011 Alamo Group Inc.

Operation Section 4-23

OPERATION

Breakaway may occur momentarily during normal work should an extra thick or dense patch of vegetation be
encountered. In these instances tractor forward motion may be maintained with care. Where breakaway has
occurred as a result of contacting a post or tree etc. the tractor must be halted and the controls of the machine
utilized to manoeuvre the head away from the obstacle. NEVER CONTINUE FORWARD MOTION TO DRAG
THE HEAD AROUND THE OBSTACLE IN BREAKBACK POSITION.

OPERATION

9.1 POWERED SLEW

The slew feature allows a 95° arc of powered arm movement on the working side from right angles to the
tractor to 5º beyond the direct line astern.
The feature is required to place the machine in the transport position but can also be used to sweep the arm to
and fro whilst cutting awkward areas and corners thus avoiding the need to constantly re-position the tractor.
To operate in this way 'SLEW' must be selected on the control assembly.
If breakaway occurs the slew motion must be reversed to allow the slew breakaway relief valve to re seat and
the ram to become operable again.
Extra care must be taken when working in 'SLEW’ mode with the reach fully in – IT IS
POSSIBLE FOR THE FLAILHEAD TO HIT THE TRACTOR OR MACHINE FRAME.

Operation Section 4-24

OPERATION
10. WIRE TRAP
The flail head is equipped with a wire cutting edge
welded into the underside. This is to ensure that the
ends of any wire that may be entwined in the rotor are
cut and fall within the confines of the flail head. This
plate should not be interfered with in any way. Any wire
caught in the rotor must be immediately removed (see
below).
•
•
•

Select rotor 'OFF' and wait until it has stopped
rotating.
STOP the tractor and only then remove wire.
Do not reverse the rotor in an attempt to unwind
any wire.

11. Rotor Operating Speed
Ensure that the rotor control lever is in the ‘STOP’ position before engaging the PTO shaft. Allow the oil to
circulate for a minute or so before operating the armhead levers. Position the fail head in a safe position,
increase the engine speed to a high idle and move rotor control lever to ‘START’. After initial surging the rotor
will run at an even speed.

12. Forward Speed

The material being cut determines tractor forward speed. Forward speed can be as fast as that which allows
the flail head sufficient time to cut the vegetation properly.
Too fast a speed will be indicated by over frequent operation of the breakaway system, a fall off in tractor
engine revs and a poor finish to the work leaving ragged uncut tufts and poorly mulched cuttings.

15. DRIVING THE TRACTOR AND IMPLEMENT

OPERATION

Safe tractor transport requires the operator to possess a thorough knowledge of the model being operated
and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to
handle the weight of the boom and the tractor operating controls are set for safe transport. To ensure safety
while driving the tractor with a boom, review the following.
Read all safety instructions. Decals on the Boom warn you of particular and multiple hazards. Some decals
are attached close to part of the Boom where there is a possible hazard. Read and make sure you
understand the safety messages before you operate the implement. Keep all decals clean and readable.
Replace lost or damaged decals, refer to safety section for more information.
Power for operating the mower is supplied from the tractor PTO. Refer to your tractor manual instructions for
engaging and disengaging the PTO. Start the tractor and bring the engine speed up to normal operating 540
PTO speed. Always engage the PTO at low engine RPM and run the mower for a short period until all air is
removed from the hoses. Keep all person's well clear of mower since blades can throw objects with great
velocity for a considerable distance! KEEP CLEAR! OPS-B- 0005

Never operate the Tractor or Implement until you have read and
completely understand this Manual, the Tractor Operator’s Manual, and
each of the Safety Messages found in the Manual or on the Tractor and
Implement. Learn how to stop the tractor engine suddenly in an
emergency.
Never allow inexperienced or untrained personnel to
operate the Tractor or Implement without supervision. Make sure the
operator has fully read and understood the manuals prior to operation.
(SG-4)

Always maintain the safety signs in good readable condition. If the safety signs are missing,
damaged, or unreadable, obtain and install replacement safety signs immediately. (SG-5)

This Implement may be wider than the Tractor. Be careful when operating or transporting
this equipment to prevent the Implement from running into or striking sign posts, guard rails,
concrete abutments or other solid objects. Such an impact could cause the Implement and
Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.
Never allow the Implement to contact obstacles. (S3PT-12)
BEFORE leaving the tractor seat lower the implement, set the parking
brake and/or set the tractor transmission in parking gear, disengage the
PTO, stop the engine, remove the key, and wait for all moving parts to
stop. Place the tractor shift lever into a low range or parking gear to
prevent the tractor from rolling. Never dismount a Tractor that is moving
or while the engine is running. Operate the Tractor controls from the
tractor seat only. (SG-9)

OPERATION
15.1 Starting the Tractor
The procedure to start the tractor is model specific.
Refer to the tractor operator’s manual for starting
procedures for your particular tractor. Consult an
authorized dealer if the starting procedure is
unclear. Ensure the 3-point control lever is in the
lowered position and the PTO is disengaged before
starting the tractor. OPS-U-0033

Make sure the tractor brakes are in good operating
condition. Tractor brakes can be set to operate
independently allowing single rear wheel braking
action or locked together to provide simultaneous
rear wheel braking. FOR MOST DRIVING AND
OPERATING CONDITIONS, THE BRAKE PEDALS
SHOULD BE LOCKED TOGETHER TO PROVIDE
THE MOST EFFECTIVE BRAKING ACTION.
Always disengage the tractor differential lock when
turning. When engaged the differential lock will
prevent or limit the tractor from turning. During
normal cutting conditions, locking the differential
provides no benefit and should not be used. OPSU- 0013
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
When operating down a hill or on wet or rain slick roads, the braking distance increases; use
extreme care and reduce your speed in these conditions. When operating in traffic, always
use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around
you and watch out for the other guy.

15.3 Driving the Tractor and Boom

OPERATION

Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the
tractor. Never operate the tractor at speeds that cannot be safely handled or which will prevent the operator
from stopping quickly during an emergency. If the power steering or engine ceases operating, stop the tractor
immediately as the tractor will be difficult to control.
Perform turns with the tractor and mower at slow
speeds to determine how the tractor with and
attached implement handles a turn. Determine the
safe speed to maintain proper control of the tractor
when making turns. When turning with the
implement the overall working length and width of
the unit is increased. Allow additional clearance for
the unit when turning or when passing large
obstructions.

To avoid overturns, drive the tractor with care and
at safe speeds, especially when operating over
rough ground, crossing ditches or slopes, and
turning corners. Use extreme caution when
operating on steep slopes. Keep the tractor in a low
gear when going downhill. DO NOT coast or freewheel downhill.
OPS-B- 0006

Never Leave the mower unattended while the head is in the raised
position. The mower could fall causing serious injury to anyone who
might inadvertently be under the mower. (SBM-4)

Always keep a careful lookout and use extreme care when working
around overhead obstructions. Never allow the Mower head or boom
within 10 feet of any power line. When working close to overhead
power lines consult your electric company for a safe code of operation.

IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and
understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These
manuals must be read and explained to any operator who cannot read. Never allow someone to operate the
implement and tractor without complete operating instructions.

16.1 Foreign Debris Hazards
Before mowing, inspect the area to make sure
there are no foreign objects that the mower
blades could hit or become entangled with.
Remove all foreign objects and debris. If objects
are too big to remove, mark them clearly and be
sure to prevent the mower blades from
contacting them.
If you hit a solid object or foreign debris, stop the
mower and tractor at once. Immediately idle the
engine speed and disengage the PTO. Wait for
all mower rotating motion to stop, then raise the
mower and move the tractor and implement off
the object. Inspect the area and remove, or
mark the location of the debris. Inspect the
condition of the mower and make any needed
repairs immediately. Make sure the blades are
not damaged and the carrier is balanced before
resuming operation.
Always wear your seat belt securely fastened
and only operate the tractor and mower with the
ROPS in the raised position. If the tractor or
mower hits a tree stump, rock, or bump, a
sudden movement could throw you off of the
seat and under the tractor and/or mower. The
seat belt is your best protection from falling off
the tractor and the ROPS provides protection
from being crushed during a tractor roll-over.

Operation Section 4-31

OPERATION

Before starting any operation, the operator must become familiar with the area to be worked in and any
obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special
attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.
OPS-U- 0015

OPERATION
16.2 Bystanders/Passersby Precautions
If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once,
idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the
300 foot distance. OPS-R-0024

OPERATION

Rotary Mowers are capable under adverse conditions of throwing
objects for great distances (300 feet or more) and causing serious injury
or death. Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 300 Feet UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable
condition;
-Mower sections or Wings are running close to and parallel to the ground without exposed
Blades;
-Passersby are outside the existing thrown-object zone;
-All areas have been thoroughly inspected and all foreign material such as rocks, cans,
glass, and general debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could be struck
by the blades, the area should be: inspected and large debris removed, mowed at an
intermediate height, inspected, closely with any remaining debris being removed, and
mowed again at desired final height. (This will also reduce power required to mow, reduce
wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and
make the final cut more uniform). (SRM-01)

16.3 Engaging the Power Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement
must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with
the implement in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to
the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you
hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the
implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027

Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up. (SGM-09)

1900 07/11

Operation Section 4-32

OPERATION
16.4 Operating Speed and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Do Not
exceed 2 MPH while operating. Operate the mower at its full rated PTO speed to maintain blade speed for a
clean cut. Refer to the tractor operator’s manual or the tractor instrument panel for the engine speed and gear
to provide the required operating and desired ground speed. Make sure that the mower is operating at its full
rated speed before entering the vegetation to be cut. Always start and stop cutting blades with engine near
idle.

Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death. (SG-26)

Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power
lines, or when debris and foreign objects are to be avoided. (SGM-07)

16.5 Operating the Mower
The mower is designed to cut vegetation up to 1-1/2” in diameter. Sharp blades will produce a cleaner cut and
require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and
maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving pattern
that provides the maximum pass length and minimizes turning.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the
same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining
the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and
be cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut.
Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to
access areas to be cut, make sure there are no persons or other foreign debris behind the mower before
mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to
ensure tractor and mower control is maintained. OPS-R-0026_N

1900 07/11
© 2011 Alamo Group Inc.

Operation Section 4-33

OPERATION

Ground speed is achieved by transmission gear selection and not by the engine operating speed. The
operator may be required to experiment with several gear range combinations to determine the best gear and
range which provides the most ideal performance from the implement and most efficient tractor operation. As
the severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to
maintain the proper operating PTO speed. OPS-B- 0009

OPERATION

There are obvious and hidden potential hazards in the operation of this
Mower. REMEMBER! This machine is often operated in heavy brush
and in heavy weeds. The Blades of this Mower can throw objects if
shields are not properly installed and maintained. Serious injury or even
death may occur unless care is taken to insure the safety of the operator,
bystanders, or passersby in the area. Do not operate this machine with
anyone in the immediate area. Stop mowing if anyone is within 300 feet
of mower. (SGM-02)
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)

Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
300 feet (90 m) in front and to the sides of the tractor and mower. Make sure that you can
clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,
power lines, debris and foreign objects. If you are unable to clearly see these type of items
discontinue mowing. (SGM-1)
Avoid mowing in reverse direction when possible. Check to make sure there are no
persons behind the mower and use extreme care when maneuvering in reverse. Mow only
at a slow ground speed where you can safely operate and control the tractor and mower.
Never mow an area that you have not inspected and removed debris or foreign material.
(SGM-08)

Follow these guidelines to reduce the risk of equipment and grass fires
while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accesible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.
Periodically shut down the Tractor and Mower and clean clippings and collected debris from
the mower deck. (SGM-12)

Operation Section 4-34

OPERATION
16.6 Operating the Attached Mower Heads
Refer to the Assembly Section of this manual to ensure the head is properly attached to the boom hitch and
hydraulic lines are properly connected.

Flail
•

The H48 is rated to cut material up to 1” in
diameter. The F48 is rated for 1-1/2” diameter
material.
• Setting cutting height ranges from 3/4” to 6”.
Cutting height is set by adjusting the height of
the roller assembly.
When operating near the ground or when mulching
be particularly careful that there are no bystanders
or animals within a 300 feet. Debris tends to fly out
at great speed and can injure or even cause death.

Sickle Bar
•
•
•
•

•

The Sickle Bar Cutter will cut a 5’ swath
through tough weeds and grass.
The Sickle Bar Cutter is operated attached to
the boom arm and is ideal for vegetation
maintenance
When operating the Sickle Bar correctly it will
give you a fast, efficient, and cost-effective
method of vegetation maintenance.
The Sickle Bar will also cut vegetation through
tough weeds under water, ideal for maintaining
ponds, creeks, and other areas that may be
under shallow water.
When operating the unit be sure there are no
bystanders or animals within 300 feet of the
unit. OPS-B- 0049

16.7 Shutting Down the Attached Head

OPERATION

To shut down attached mower head, first bring the
tractor to a complete stop. Decrease engine RPM
to idle then disengage cutterhead. The mower head
will come to a complete stop within a suitable
amount of time. Do not engage or disengage the
cutterheads at a high RPM unless there is an
emergency situation.

Park the tractor on a level surface, place the
transmission in park or neutral and apply the
parking brake, shut down the engine, remove the
key, and wait for all motion to come to a complete
stop before exiting the tractor. OPS-B- 0011_K

17. TRACTOR, BOOM, AND ATTACHED HEAD STORAGE
Properly preparing and storing the unit at the end of the season is critical to maintaining its appearance and to
help ensure years of dependable service. The following are suggested storage procedures:

Operation Section 4-36

OPERATION
•
•
•
•

Never allow children to play on or around Tractor or Implement. Children can slip or fall off
the Equipment and be injured or killed. Inadvertent contact with controls can cause the
Implement to shift or fall crushing themselves or others. (SG-25)
BEFORE leaving the tractor seat lower the implement, set the parking
brake and/or set the tractor transmission in parking gear, disengage the
PTO, stop the engine, remove the key, and wait for all moving parts to
stop. Place the tractor shift lever into a low range or parking gear to
prevent the tractor from rolling. Never dismount a Tractor that is moving
or while the engine is running. Operate the Tractor controls from the
tractor seat only. (SG-9)

Always shut the Tractor completely down, place the transmission in park, and set the
parking brake before you or anyone else attempts to connect or disconnect the Implement
and Tractor hitches. (S3PT-15)

18. TRANSPORTING THE TRACTOR AND IMPLEMENT
Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind
when you finish working in an area. Therefore, the operator must employ good judgement and safe operation
practices when transporting the tractor and implement between locations. By using good judgement and
following safe transport procedures, the possibility of accidents while moving between locations can be
substantially minimized. OPS-U- 0017

Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)

Operation Section 4-37

OPERATION

•
•

Thoroughly clean all debris from boom and

tension link and the rear cross member of the tractor cab.

OPERATION

20. TRANSPORT POSITION-Head Removal

With the flail head removed the arms are fully folded but the lift ram remains retracted. If the lift ram is extended
the weight of the arms will cause the balance of the machine to go over centre causing the tension link to crash
into the rear cross member of the tractors cab.
During transport the 'SLEW’ mode must ALWAYS be selected on the control assembly.

Operation Section 4-39

OPERATION

Before transporting the tractor on a public roadway
or boarding a trailer for transport, the tractor brake
pedals should be locked together. Locking the
pedals ensures that both wheels brake
simultaneously while stopping, especially when
making an emergency stop.
Use extreme caution and avoid hard applications of
the tractor brakes when towing heavy loads at road
speeds. Never tow the implement at speeds
greater than 20 MPH (32 kph). OPS-U- 0018

20.1 Transporting on Public Roadways
Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor
must be equipped with all required safety warning features including a SMV emblem and flashing warning
lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for
automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.
Check your side view mirrors frequently and remember that vehicles will approach quickly because of the
tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than
the tractor tire width and/or extends beyond your lane of the road.
Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a
public road. OPS-U- 0019

NOTE: Ensure that the mower sections are fully raised and that the transport locks are engaged for each
section.
Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH. (STI-06)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clearly visible and legible. When transporting the
Equipment use the Tractor flashing warning lights and follow all local
traffic regulations. (SG-6)

Operation Section 4-40

OPERATION

Make sure that all tractor flashing warning lights,
headlights, and brake/taillights are functioning
properly before proceeding onto public roads.
While newer model tractors have plenty of lighting
to provide warning signals and operating lighting,
most older models where only equipped with
operating lights. Consult an authorized tractor
dealer for lighting kits and modifications available
to upgrade the lighting on older tractor models.
OPS-B-0015

When operating on public roads, have
consideration for other road users. Pull to the side
of the road occasionally to allow all following traffic
to pass. Do not exceed the legal speed limit set in
your state or municipality for agricultural tractors.
Always stay alert when transporting the tractor and
mower on public roads. Especially in busy cities,
the boom extends to right farther then the tractors
width, so be careful there are no bystanders, poles,
large obstructions or any vehicles that may be in
path of the mower head or boom. Use caution and
reduce speed if other vehicles or pedestrians are in
the area. OPS-B- 0016

Operation Section 4-41

OPERATION

The SMV (Slow-Moving Vehicle) emblem is
universal symbol used to alert drivers of the
presence of equipment traveling on roadways at a
slow speed. SMV signs are a triangular bright
orange with reflective red trim for both easy day
and night visibility. Make sure the SMV sign is
clean and visible from the rear of the unit before
transporting the tractor and implement on a public
roadway. Replace the SMV emblem if faded,
damaged, or no longer reflective. OPS-U- 0020

OPERATION

Reduce speed before turning or applying the brakes.
Ensure that both brake pedals are locked together
when operating on public roads. OPS-U- 0023

When transporting Boom Mower on a truck or trailer, the height or width
may exceed legal limits when the boom is in the transport position.
Contact with side or overhead structures or power lines can cause
property damage or serious injury or death. If necessary lower boom to
reduce height and/or remove mowing head to reduce width to the legal
limits. (SBM-8)

20.2 Hauling the Tractor and Implement
Before transporting a loaded tractor and implement,
measure the height and width dimensions and
gross weight of the complete loaded unit. Ensure
that the load will be in compliance with the legal
limits set for the areas that will be traveled through.
OPS-U- 0024_TK

Operation Section 4-42

OPERATION
Use adequately sized and rated trailers and
equipment to transport the tractor and implement.
Consult an authorized dealer to determine the proper
equipment required. Using adequately sized chains,
heavy duty straps, cables and/or binders, securely tie
down both the front and rear of the tractor utilizing the
proper tie down locations as specified by the tractor
manufacturer. OPS-U- 0025

While hauling the tractor and implement, make
occasional stops to check that the tractor and
implement have not moved or shifted and that the
securing chains have maintained tension. If during
transport a hard braking, sharp turning, or
swerving action was performed, stop at the next
safe location to inspect the security of the load.
NOTE: Always transport per you state law regulations for tie down requirements. OPS-U- 0026_TK

Operation Section 4-43

OPERATION

Arrange the chains so that when tightened, the
chains are pulling downward and against
themselves. Carefully tighten the securing chains
or other fasteners using boomers or binders to
apply maximum tension. Use extreme care when
attaching and removing the securing devices as
the extreme tension involved when released has
the potential to inflict serious injury.

PARTS INFORMATION
PARTS INFORMATION
Rhino mowers use balanced and matched system components for blade carriers, blades, cuttershafts, knives,
knife hangers, rollers, drivetrain components, and bearings. These parts are made and tested to Rhino
specifications. Non-genuine "will fit" parts do not consistently meet these specifications. The use of “will fit”
parts may reduce mower performance, void warranties, and present a safety hazard. Use genuine Rhino
mower parts for economy and safety. (SPRM-1)

LUBRICATION INFORMATION
General
Refer to the lubrication diagram and grease daily all the points shown.
1. Power take-off shaft - The PTO shaft should be regularly examined to ensure that it is in good condition
together with the guards. The universal joints should be greased very sparingly, i.e., one shot a week.
NOTE: Overgreasing a universal joint will blow out the cork or neoprene sealing rings that exclude the dirt from
the needle bearing inside.

3.
4.

The two halves of the plastic guard should be checked daily to ensure that they can spin freely on the
shaft. The nylon slip rings which support the guard on the drive shaft should be lightly greased at weekly
intervals.
The telescoping drive shaft should be similarly separated and grease applied to the internal shaft at
approximately 100 hour intervals.
Your Boom uses greased bushings that need lubrication, and with proper lubrication should last the
lifetime of the machine.

Maintenance Section 5-3

MAINTENANCE

SEE YOUR RHINO DEALER

MAINTENANCE

PTO SHAFT
Regularly check the PTO guards for damage and ensure the anti rotation chains are in place and that their
anchor points are in good condition.
Make sure the PTO shield, integral driveline shields, and input shields
are installed when using PTO-driven equipment. Always replace any
shield if it is damaged or missing. (S3PT-8)
KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement
and possible serious injury or death. (SG-24)

Maintenance Section 5-4

MAINTENANCE
PTO LUBRICATION
Lubricate the shaft at the points shown below at the intervals indicated using N.L.G.I. #2 Grease.

Oil Supply
Check daily the oil level in the reservoir.
No fixed time period can be quoted for oil changes as operating conditions and maintenance standards vary so
widely. Burnt and scorched oil odors and the oil darkening and thickening are all signs of oxidation and indicate
the oil should be changed.
Moisture which results from condensation can become entrapped in the oil and cannot be removed by filtration
so that contamination is a progressive factor.
Contamination can be reduced by:
1. Cleaning off around the reservoir cap before removal, and keeping that area clean.
2. Using clean containers when replenishing the system.
3. Regular servicing of the filtration system.

Filtration Maintenance
A 125-micron suction strainer and a low-pressure 10-micron full flow return line filter protect the machine.
Suction strainer
The strainer is permanently fixed within the reservoir.
Should symptoms of pump cavitation or spongy intermittent operation occur the tank must be drained and
flushed out with a suitable cleaning agent e.g. clean diesel oil.
Return Line Filter
The elements should be changed after the first 50 hours and thereafter at 500-hour intervals. It is important to
note hours worked as if the filter becomes blocked an internal by-pass within the canister will operate and no
symptoms of filter malfunction will occur to jog your memory.

HYDRAULIC HOSES
The condition of all hoses should be carefully checked during routine service of the machine. Hoses that have
been chafed or damaged on their outer casing should be securely wrapped with waterproof adhesive tape to
stop the metal braid from rusting. Hoses that have been suffered damage to the metal braid should be changed
at the earliest opportunity.

Maintenance Section 5-5

MAINTENANCE

HYDRAULIC SYSTEM

MAINTENANCE

Hose Replacement
1. Replace one hose at a time to avoid the risk of wrong connections.
2. When the hose is screwed to an additional fitting or union, use a second spanner on the union to avoid
breaking both seals.
3. Do not use jointing compound on the threads.
4. Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing or trapping before tightening
hose end connections.
Before changing hoses, study the installation. These are carefully calculated to prevent hose damage during
operation. Always replace hoses in exactly the same manner. This is especially important for the flail hoses
where they must be crossed, upper to lower, at the dipper and head pivots.

Hose Warranty
Warranty is limited to replacement of hoses which have failed due to faulty materials of manufacture. Warranty
will not be considered on hoses that have suffered damage by abrasion, cuts or being pinched or trapped while
in work. Neither will a claim be considered where a hose end has been damaged by a blow or where the
threads or unions have been damaged by overtightening.

Soft Seal hose connections are capable of holding pressure when the nut is only ‘finger tight’. It is therefore
recommended that when dismantling, the hose be manually flexed to relieve any residual pressure with the
retaining nut slackened prior to complete disassembly.

Maintenance Section 5-6

MAINTENANCE
CABLES

NOTE: Be careful in determining the correct cable connections on both the control unit and the valve in the
event of cable replacement.
NOTE: Be careful in determining the correct cable connections on both the control unit and the valve in the
event of cable replacement.

PTO GEARBOX
Refill the gearbox after the first initial 50 hours and thereafter yearly or 500 hour intervals. or whichever comes
first.
Drainage of the gearbox for an oil change is via the drain plug located on the base of the gearbox. To refill or for
‘topping up’ remove both plugs indicated below and fill gearbox via the filler plug to a point where the oil starts
to run from the level plug orifice – replace plugs and tighten securely. Fill with multipurpose gearbox oil P/N
00786250.

STORAGE
If machine is be left standing for an extended period of time, lightly coat the exposed portions of the ram rods
with grease. Subsequently, this grease which becomes contaminated with dust and grit should be wiped of
before the rams are next moved.
If the machine has to be stored outside, tie a piece of tarpaulin or canvas over the control assembly. Do not use
a plastic fertilizer bag which could lead to rapid corrosion.

Maintenance Section 5-7

MAINTENANCE

The cables operate on a push/pull system with the spool centering springs always returning the spool to the
neutral position when the handle is released.
Care should be taken during installation and operation to ensure that the cables are not trapped or kinked. Any
abrasion or damage to the outer casing should be sealed with plastic insulation tape to avoid moisture
penetrating.
No routine adjustment of the cables are necessary as they do not stretch. The threaded collar is correctly
adjusted when the lever is in a vertical position in its housing allowing an equal amount of travel in either
direction.
On no account should any attempt be made to lubricate the cables which are assembled
with a special lubricant during manufacture.

FLAILHEAD

Maintenance Section 5-11

MAINTENANCE

1. Frequently inspect the rotor assembly for damaged or missing flails. Bolts and nuts securing the flails to the
rotor should be regularly checked and kept tight. The correct torque setting for these locknuts is 135 Nm
(100 lbs/ft.). Use only the correct flail bolt and locking nut. Check the flail pivot bushes for possible damage
or wear. They do not require oil.
2. Do not attempt to run the rotor with flails missing. Imbalance will cause severe vibration and can rapidly
damage the rotor shaft bearings. As an emergency measure, if a flail is broken off or lost, remove another
on the opposite site of the rotor to retain balance. Always replace flails in opposite pairs and never match up
a new flail with a resharpened one which will of course be lighter.
3. Blunt flails absorb a lot of power and leave an untidy finish to work. They should be sharpened on a
grindstone or with a portable grinder periodically.
4. Wear protective gear when sharpening flails.
5. Ensure that the bearing housings and hydraulic mounting nuts and bolts are kept tight. They should be
checked during servicing.

obstrucciones elevados y dañar cables y líneas telefónicas, y posiblemente causar lesiones. He explicado que
el brazo o cabezal extendido, o el brazo retraído, puede entrar en contacto con cables de alimentación y
causar lesiones o la muerte por electrocución, y que el operador es responsable de evitar dichos riesgos.

•

MÁQUINAS HIDRÁULICAS: He explicado la necesidad de usar aceite hidráulico limpio, cambiar los filtros
según las instrucciones, detener filtraciones, prevenir daños por operar con aceite demasiado caliente, cuidar
las mangueras, usar mangueras del tipo correcto, mantener la presión operativa especificada y prevenir el
posible riesgo de que el aceite penetre en la piel.

•

LÍNEAS DE CONDUCCIÓN: Me he asegurado de que todos los protectores de líneas de conducción, de caja
de engranajes y otros están en buenas condiciones de reparación y firmemente sujetados para prevenir
lesiones por enredo u objetos arrojados.

•

IMPLEMENTOS: He explicado que los deflectores, protectores de cadena o faldones sólidos se deben mantener en buenas condiciones de reparación y se deben instalar, excepto en zonas donde personas, vehículos,
ganado u otros bienes no corran peligro por objetos arrojados, y en los casos en que dichos equipos de seguridad impedirían un desempeño razonable de la cortadora en su tarea asignada.

Video de cortadora AEM

A fin de reducir la tasa de accidentes y mejorar la operación segura de las cortadoras, Alamo Group Ag Division
se ha asociado con otros fabricantes de la industria para desarrollar el video y la guía de Prácticas de Seguridad
para Cortadoras Industriales y Agrícolas AEM/FEMA.
El video explica a los operadores de tractores y cortadoras las prácticas seguras que deben adoptar cuando
utilizan cortadoras industriales y agrícolas. Es importante que todos los operadores de cortadoras aprendan
cómo operar sus equipos de corte y puedan reconocer los posibles peligros que pueden surgir al operar una
cortadora. Este video, en conjunto con el manual del operador de la cortadora y los mensajes de advertencia
que se encuentran en la cortadora, serán muy útiles para complementar este aprendizaje tan importante.
Es posible que su distribuidor autorizado de Rhino le haya mostrado este video y le haya entregado una copia
en DVD cuando adquirió su cortadora. Si usted o algún operador de cortadora no vio el video: mire el video, lea
este Manual del Operador, y complete la Guía del Video antes de operar su cortadora nueva. Si no comprende
alguna de las instrucciones del video o del manual del operador, o si tiene alguna pregunta acerca de la
operación segura, comuníquese con su supervisor, con el distribuidor o con Alamo Group Ag.
Si desea recibir una copia del video en VHS, envíe un mensaje de correo electrónico a AEMVideo@alamogroup.com o un fax al (830) 372-9529, o envíe por correo una copia rellenada del formulario que se encuentra al
dorso de esta página a AEM VHS Video 1502 E Walnut Street, Seguin, TX 78155, y solicite la versión en VHS.
Indique su nombre, dirección postal, modelo de cortadora y número de serie.
Cada uno de los operadores debe recibir capacitación para cada equipo (tractor y cortadora), comprender el uso
previsto, y comprender los posibles peligros antes de operar el equipo.
La informacion y material mecionado en la informacion anterior junto con el Manual de Operador puede asistir
en cumplir con los requisitos de OSHA para el entrenamiento anual del Operador.
REQUISITOS DE ENTRENAMIENTO DEL OSHA

Instrucciones del operador. A la hora de la asignación inicial y por lo menos anualmente después de eso, el
empleador mandará a cada empleado quien opera un tractor agricola o implemento en las practicas de
operación segura y el mantenimiento de el equipo con el cual el empleado esté, o estará implicado y de
cualquier otras prácticas dictados por el ambiente laboral.

Al propietario/operador/distribuidor

adecuada. Si el manual se extravía o se daña, puede solicitar otra copia sin cargo a un distribuidor autorizado de
Rhino o descargarlo del sitio web de Rhino (www.servis-rhino.com).
ANTES DE COMENZAR LEA, COMPRENDA y SIGA la información incluida en este manual, el Manual de
Seguridad de la Cortadora AEM y el manual del operador del tractor para conocer cómo operar la máquina y
realizar tareas de servicio correctamente. De lo contrario, podría sufrir lesiones u ocasionar lesiones a terceros.
Todos los implementos con partes móviles son potencialmente peligrosos. Cada esfuerzo ha sido hecho para
asegurar que la màquina esté segura, pero los operadores deben evitar entrar en prácticas peligrosas y seguir las
instrucciones escritas que son proporcionadas. El fabricante ha diseñado este implemento para ser usado con
todos sus equipos de seguridad correctamente sujetados para minimizar la probabilidad de accidentes.
LA SEGURIDAD PRIMERO. Lea con atención la totalidad de la sección de seguridad de este manual antes de
operar el equipo. No permita que nadie opere el equipo sin haber leído y comprendido la totalidad de este manual.
Comuníquese con el distribuidor si necesita explicación sobre alguna instrucción que no haya comprendido del
todo.
Los cuidados que brinde a su Implemento Rhino determinarán en gran medida su satisfacción con el desempeño
y la vida útil del equipo. Lea con atención y siga las instrucciones de este manual para comprender cabalmente su
nuevo implemento, su uso previsto, y sus requisitos de servicio.
Todas las referencias que se hacen en este manual a derecha, izquierda, frontal, trasero, arriba y abajo

La información sobre repuestos se encuentra por separado en el Manual de Partes. Las cortadoras Rhino utilizan
componentes del sistema equilibrados y coincidentes para porta cuchillas, cuchillas, ejes de corte, hojas, ganchos
para hojas, rodillos, componentes de los engranajes, y cojinetes. Estas partes se fabrican y se prueban según las
especificaciones de Rhino. Las partes compatibles no genuinas no siempre cumplen con estas especificaciones.
El uso de partes no genuinas puede perjudicar el desempeño de la cortadora, anular la garantía y presentar un
riesgo para la seguridad. Use partes genuinas Rhino para ahorrar dinero y maximizar la seguridad.
Para referencia futura, registre el número de modelo y el número de serie de RHINO que ha adquirido.
